Abstract

An audio signal is encoded. The signal is first divided into bands (600) for each a band a "yardstick" signal element is selected (608), and its quantized magnitude used for allocating lists, with less accuracy for quanitzing non-yardstick signal elements (624) the encoded signal is later decoded (918, 926). <IMAGE>
